Thread: Rear brake pad wearing down on an angle - 2006 Grand Prix GXP

Title says most of it, any ideas? Here is more info.

1) Brake pads replaced 2x. Rotors replaced once.
2) After about a month the rear, passenger side brakes start squeaking.
3) upon inspection, one of the pads is wearing down sideways (along the length of the pad).
4) It is the pad touching the piston.

bent caliper would be my guess. both pads wearing angled? or what one? is angled?

I'd be looking into the bracket and slides.

Only 1 pad is wearing our on an angle, and that is the inside one. The one touching the piston.

The one with the rubber sleeve is no doubt swelled and stuck.
I just tossed one last week when doing my strut mounts in the rear

Silicone with ptfe doesn't break down rubber

If one of the caliper pins was stuck, wouldn't either the left/right side be wearing down fast rather than top/bottom? And if that is it, you are saying a new boot would solve it?

In general what should my next steps be? Replace the boots, grease up the pins and try again?

take the caliper off, then the two bolts with the boot that holds the caliper on, clean them both and the holes they live in with brake cleaner then grease them both and work them in and out of the caliper till they slide like butter, add more grease if need be. then bolt it back together.

I had the same thing last year. One of the caliper slides was sticking.
